SPECIFICATION forming part of Letters Patent No. 515,267, dated February20, 1894.

Applicationfiled May 9, 1893.

To all whom it may-concern:

Be it known that we, J QHN A. WELTON and GEORGE W. WELTON, J r.,citizens of the United States, .and residents of Canton, county ofStark, State of Ohio, have invented a new and useful Improvement inSteam- Generators, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, makingpart of this specification.

Our invention relates to improvements in steam generators and consistsof certain features of construction and combination of parts as will behereinafter described and pointed out in the claim.

Figure 1, of the accompanying drawings is an end view of a steamgenerator, with aportion of the head cut away to show the interior,illustrating our invention. Fig. 2, is a side view of a fragment of theboiler and the end of steam dome; and Fig. 3, a section of a fragment ofsteam dome, and connecting pipe.

Referring to Fig. l, A represents the boiler which may be made of anysuitable material andis formed substantially as shown having a greaterVertical than horizontal diameter.

For the purposes of this application we have shown a boiler four feethigh and twenty inches through horizontally, and six feet long, havingvertical sides and circular top and bottom as shown; but otherproportions may be substituted when preferred. l

About central to the body A, of the boiler, is provided a partitionplate B, extending from one end of the boiler to the other, and frompoints a distance from the bottom and top as shown at a. To secure saidpartition plate B in position, rivets or bolts as b are provided, havinga threaded central portion 0, adapted to be turned into threadedapertures-in the plate B, the end portions to pass through correspondingapertures in the sides of the boiler in and over which they are united,the bolts serve as stay bolts to the sides of the boiler as well as asupport for the plate B. There are also provided on each side of thebody of the boiler two series of over- Serial No. 473,613. (No model.)

lapping return pipes d as shown in Figs. 1 and 2.

At the upper end portions of the boiler A, are provided upwardlyprojected tubes 0, communicating with a steam dome as shown.

The generator or boiler is inclosed by a brick wall E at the lowerportion, of which is provided an opening or door-way through which fuelis passed to the grate F.

G represents a check plate placed in the dome over the end of the tubes0 to check the flow of water from the boiler to the dome.

In operation the generator is filled with water up to and including aportion of the dome, the tubes 0 being always filled, tire is made uponthe grate F, the flame and heat striking against the side of thegenerator, passes up and embracing the return tubes (1 on the front andover the top of .A, about the tubes 0, and down about the return tubeson the rear side, and out at the bottom of the wall to the stack asindicated by the arrows. The plate B checks the flow of water transversethe body of the boiler as ejected from the return tubes, and to cause itto pass about the ends of the plate, the greater heat on the front side,the water will flow up on the front and over and down on the rear sideof the plate. 1

Having thus fully described the nature and object of our invention, whatwe claim is The combination in a steam generator of a body or boilerportion of less diameter in cross section than vertical or longitudinalsection, the vertical partition plate B, stay bolts 1), threaded attheir centers and engaging with correspondingly threaded apertures insaid plate and their ends connected with the boiler, the return pipes (1connected with the boiler, the dome D and the deflecting plate G,substantially as herein described.

In testimony whereof we have hereunto set our hands this 25th day ofApril, A. D. 1893.
